RX8 system install...help please.

Ahsmo · Post by **Ahsmo** » Wed Mar 12, 2008 8:43 am

A kid at my school wants me to help him install a system in his RX8.

I also need to help pick out the equipment.

I would like to use all PG components for this install because...I am a brand whore. Granted, I am open to suggestions. Thus far I have come up with this but I am unsure if the amp I have picked has enough balls to run a sub well.

Price objective: $1000
Car: RX8
Music preference: Rock for normal listening, bullshit squarewave rap for showing off to stupid kids.

Going to use the stock deck so I need a hi to low converter. Is it worth getting a fancy JL audio converter?

Amp: RSD 500.4
Front Components: RSD6.5
Rear fill: nope
Sub: 10inch RSDc

4 guage amp kit

Anyone think I am steering him wrong here? I am not confident that the RSDc will be getting enough power.

I run my RSDc 12 on the rear of my Ti500.4, and it whoops my ass. A 10 should be fantastic

Just use a PG SLD44 for your converter.

After checking through google a bit, it looks like the stock non-bose headunit outputs a flat signal, so an SLD44 would work for sure.

I would go with the

rsd600.1
rsd250.2
rsd65cs
rsdc10d4

and buy some install gear from knu

(or just bulk order the 4awg, and dist blocks etc)

that should put him right around 800-850

man... you guys are good.

fowler. I would prefer those amps to a single 4 channel but for simplicity's sake the 4 channel may more than meet this guy's needs.

...He thinks his 5.1 logitec system sounds better than my 2.0 studio monitor setup

If I can convince him to spend a little extra I may go with 2 RSDc 10s and a 600.1

I am going to use one of these boxes: http://cgi.ebay.com/ebaymotors/Mazda-RX ... QQtcZphoto

I have no tools to use for this install so building my own box or glassing something is out of the question. Besides, I doublt I could build a box for much cheaper or better.

that IS a sweet box. two rsdcs for sure. or even normal rsd's if the budget wont allow

running two power wires isnt two much harder then 1

I've talked to a few installers who complain that the 'Cleansweep' has it's issues. Noise problems as well as delays in processing which makes it's own wierdness.

If the PLD44 had a 3rd set of outputs for subwoofer with a remote volume control it would be the shiznit!

Box might be way too big for a single RSDc 10... they need only ~0.6cuft each.

Dude! Good idea.

I do prefer though to have my subwoofer volume limited at the amp, instead of at the processor. That way I get an 8 volt signal going to the back, which is then internally limited in the amplifier, instead of sending a lower voltage signal instead. Fortunately most of our amps have that taken care of already, but I can see how that would be very handy in many other cases

Good point. Not all amps are created equal as you mention. Having that ability would make it universal.

I think I could ask them to parition the box off.

Would .75 cuft be too much? I figured it would be negligible.

If that's before woofer displacement, then you're fine.

Heck with all that extra airspace you could throw a sizable port in it. No sense letting half of that room go to waste

Well I got the guy to go with two subs. He wants to order soon and install within 3 weeks.

Thanks guys.

if you use the SLD44 I can walk you through how to mod it and use it as an AUX in (another idea that PG wouldn't hear).

I'd like to know that!^^^

The custom built box can't be efficiently built for that price.

As far a box volume goes, couldn't you just add properly secured wood strips inside to bring it down to a "better" level? Comments?

That would be useful. Thank you!

With the driver in place, it should be close to .6

The boxes are good quality, I have seen boxes he has built for the 350z. I have gotten into arguements with the guy over a few things in the past but his boxes are nice.

And you couldn't mention this before because.....??? I also would like to hear this, although it would probably be over my head. You have seen me in action with my compy!!
